The genus Saguinus comprises three principal clades that diverged in the Middle to Late Miocene. Their taxa are ecologically differentiated and allopatrically distributed. These clades were recently recognized as different genera, Saguinus, Tamarinus and Oedipomidas. In Tamarinus, the phylogenetic relationships among species/subspecies are poorly u...

Although the Amazon has the greatest diversity of primates, there are still taxonomic uncertainties for many taxa, such as the species of the Saguinus mystax group. The most geographically broadly distributed and phenotypically diverse species in this group is S. mystax, and its phenotypic diversity has been recognized as three subspecies—S. mystax...

The Amazon forest has the highest biodiversity on Earth. However, information on Amazonian vertebrate diversity is still deficient and scattered across the published, peer-reviewed, and gray literature and in unpublished raw data. Camera traps are an effective non-invasive method of surveying vertebrates, applicable to different scales of time and...

Coleções zoológicas são instituições que abrigam espécimes testemunho da biodiversidade, fornecendo suporte para o desenvolvimento científico e inovação em várias áreas do conhecimento, que muitas vezes apenas são possíveis devido à existência dessas coleções. A Coleção de Mamíferos da Universidade Federal de Lavras (CMUFLA) foi iniciada em 2004, a...

Coleções biológicas são importantes repositórios sistematizados da vida em nosso planeta, oferecendo inúmeras oportunidades de pesquisa, treinamento e aprimoramento de pesquisadores. As amostras e dados mantidos em coleções são cada vez mais usados para testar hipóteses biológicas. A Coleção de Mamíferos do INPA é a segunda maior coleção de mamífer...

The Roosevelt–Rondon Expedition marmoset Mico marcai was first collected in 1914 and all information on this primate previously came from three skins brought back by this expedition. As a result, M. marcai is categorized as Data Deficient on the IUCN Red List. As the presumed range of M. marcai lies on the path of the advancing arc of deforestation...

As populações da Amazônia são extremamente vulneráveis à COVID-19 devido ao intenso fluxo entre as localidades rurais e as sedes municipais e à falta de infraestrutura de saúde básica adequada na região. O objetivo deste estudo foi (1) avaliar o efeito da medida de distanciamento social sobre a disseminação da COVID-19 em sedes municipais e (2) est...

The tick fauna of Brazil is currently composed by 72 species. The state of Amazonas is the largest of Brazil, with an area of ≈ 19% of the Brazilian land. Besides its vast geographic area, only 19 tick species have been reported for Amazonas. Herein, lots containing ticks from the state of Amazonas were examined in three major tick collections from...

Primates in three protected areas in the middle Solimões basin, Brazilian Amazon ABSTRACT-Species inventories are essential for protected area management plans. Here we report on primate inventories in three protected areas (PAs) in the middle Solimões basin in the state of Amazonas, Brazil. We surveyed two areas of sustainable use-the Rio Jutaí Ex...

The most representative group among mammals are rodents for presenting high ratio to the total of species. However, rodents are considered a "taxonomic chaos" and some species such as Blarinomys breviceps, Bibimys labiosus, Akodon lindberghi and Pseudoryzomys simplex are little known. That can be explained because of low occurrence of small terrest...
